'ROTARY SHEARING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 650,054, dated May 22,1900.

Application filed June 3,1899. Serial No. 719,322. (No model.)

To all whom it may concern: Be it known that we, J OHN HENRY SILLEY andWALTER WILLIAM Bacon, engineers, of Sydney, in the Colony of New South\Vales, have invented certain new and useful Improvements in RotaryShearing-,Machines; and we do herebydeclare the following to be a full,clear, and enact description of said in= vention, such as will enableothers skilled in the art to which-it most-nearly appertains to make,use, and practice the same.

This invention relates to improvements in shearing-machines, and moreparticularly to sheep-shearing machines.

The objects of this invention are, first, to provide a machine in whichthe vibration of the working parts is reduced to a minimum; second, tosubstitute a rotary movement of the cutting blades for the reciprocatingmovement generally adapted in shearing machines;

third,'to provide a machine in which the cut-' ting-bladesare easilyinterchangeable, and, fourth, to provide'a machine which can bemanufactured cheaply and which consists of few working parts. 7

To make our invention clear, we shall refer at once to the accompanyingdrawings.

Figure 1 is a plan of-our machine with top cover removed. Fig. 2 issection through the machine complete; Fig. 3, an elevation showin g endof tension-lever and poirtion of revolving disk.

A is the comb.

B B are adjustable cutting blades which are held in position by'thescrews 0 G, and said blades may be made in any desirable shape.

D is the disk or cutter-head to which the cutting-blades B B are fixed.This disk has a central cut-out portion on its inner side- 'i. a, theside toward the combto receive an inwardly-extending portion of saidcomb, whereby the disk is journaled upon the comb.

E is a spindle by means of which the disk D, carrying the cutting-bladesB B, is revolved. The spindle E may be an integral part of disk D or maybe attached thereto in any suitable manner.

F is a shoulder or boss on the top side of disk D and forming partthereof, in which is formed an annular recess G. In this annular recessis formed a raceway for a number of steel balls X X, and a ring orwasher H is I fitted'in said recess on top of the balls, thisconstruction being provided for the purpose of reducing the frictionwhen the desired tension is applied to keep the cutting-blades B B inclose contact with the comb A.

J is a spring-lever, one end of Which fits over the spindle E and restson ring or washer H, the other end being retained in a socket J K is athreaded fixed pillar which passes through an aperture in center of thespring lever J.

L is a tension-nut on fixed pillar K, provided for the purpose ofregulating the T1811. sion, as when the nut L is screwed down the end Jof lever J is pressed down on washer H, thus keeping the cutting-bladesB B in close contact with the comb A. The end J of lever J which fitsover spindle E, is provided on the under side with projections or teethJ Fig. 3, which fit int-o groovesiu the Washer or ringH for the purposeof prevent ing the washer H from revolving.

M M are small set-screws provided for the purpose of holding the washerH in position when the lever J is removed,the washer having its outerface grooved to receive saidsetscrews.

N is a spring attachment provided to lockthe tension-nut L.

P is the lower portion of the handle of the machine. 7

- Q is the upper portion of the handle of the machine.

R is a hinge, by means of which the upper and lower portions of thehandle are connected.

S is a nut holding upper portion of handle in position said nut workingupon the threaded pillar I T is a shield which is attached to the upperportion of the handle and fits over and protects the revolving disk D.

The method of operating our invention is as follows: The power istransmitted to the spindle E by means of a flexible shaft connected inany suitable manner to the said spindle and .the disk D, carrying thecutting-blades B, revolved. The bladesB B are kept in contact with thecomb A by means of spring-lever J, the pressure being regu-1 lated bytension-nut L, the revolving disk D being protected from contact withthe wool or other material to be shorn by means of. the

' shield T. I

Having now particularly describedand ascertained'the nature of our saidinvention'andil in what manner the same is to be performed, we declarethat what we claim is- 1. In an improved shearing-machina thecombination of a revolving disk having cutting-blades secured thereon,and a comb,

with a spring-lever engaging said disk and a tension-nut in contact withsaid lever; s1 1bstantially as described.

2. In a shearing-machine, acomb, a cooperating cutter-carrying head, oneof said cooperating members being relatively fixed while the other hasmovement toward and away from said relatively-fixed member, a
